Description

The Square D 8536SEO1S is a full-voltage, non-reversing magnetic motor starter in the Class 8536 Type S family, manufactured by Schneider Electric. It is also referenced as 8536SE01S and is designed for use with Three (3)-phase AC squirrel cage motors. Refer to manufacturer documentation to confirm compatibility with your specific application.

This NEMA Size 3 starter is rated for Ninety (90) Amperes at 600V AC (50/60 Hz) and is configured as a 3-pole, open-type unit with screw clamp terminations. Horsepower ratings are 25 HP at 200V, 30 HP at 230V, and 50 HP at 460/575V for three-phase motors. The control coil operates at 120V AC, and the starter includes a normally open holding circuit contact for standard 3-wire control wiring.

The overload relay section uses melting alloy thermal units rated Class 20; thermal units are sold separately and must be selected based on motor full-load current. The starter features trip-free construction — the overload relay will trip even if the reset lever is held in the reset position — and includes a manual push-to-test button with a visible trip indicator for fast field diagnosis.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
